I got the update for my S9 last week. Never had any camera issues before that at all whatsoever. Now, suddenly, my camera shows a black screen, about everybthird time Ibuse the camera, and I have to restart my phone to get it to work every time. I tried to force stop the app, but that did nothing to help. The only thing that helps is to restart my phone. And I'm sick of doing that three times a day.
